Answer: First option.
Step-by-step explanation:
Given the equation [tex]-x = 4- 3x + 6[/tex], you need to solve for the variable "x" to find its value.
Add the like terms on the right side of the equation:
[tex]-x = 10-3x [/tex]
Now you need to subtract 10 from both sides of the equation:
[tex]-x-10 = 10- 3x -10[/tex]
[tex]-x-10 =- 3x[/tex]
The next step is to add "x" to both sides of the equation:
[tex]-x-10+x = - 3x +x[/tex]
[tex]-10 = - 2x[/tex]
And finally, divide both side by -2:
[tex]\frac{-10}{-2}=\frac{-2x}{-2}\\\\x=5[/tex]
